Question

The velocities of a body executing S.H.M. are 3 cm/s and 4 cm/s when the displacements from the mean position are 4 cm and 3 cm, then the period of oscillation is
A. `(1)/(2pi) s`
B. `(x)/(2) s`
C. `(2)/(x) s`
D. `2pis`

Answer 1

Correct Answer - D
`T=2pisqrt((x_(2)^(2)-x_(1)^(2))/(v_(1)^(2)-v_(2)^(2)))=2pisqrt((9-16)/(9-16))=2pi`
